Though it is indeed just arpeggios and not even a half a minute long, I enjoyed listening to it and I love pianos added to that. It also had a bit of a melody to it and it was actually quite beautiful so I will give you a 9 for all that, even though as mentioned.. it was just arpeggios and 25 seconds long. Is it you playing or GuitarPro, Reason, other? because if it is you, you're pretty good with phrasing blazingly fast.
Well, first off thanks for the review! And, sorry to disapoint you but I'm not the one playing... I acctually did this with keyboard and mouse... and I used FL Studio.
